Abstract (en)

[origin: EP2281785A1] The glass melting furnace (12) comprises burners (13), and a ceramic membrane for separating oxygen (14) from a gas mixture. Combustion energy is partially produced by oxy-combustion during heating. The flow of oxygen supplied to the burner is regulated by characteristics including temperature, pressure and flow of the gas mixture. The oxygen separation is carried out at 600-950[deg] C under a pressure of 1x 10 6>Pa. The flow of oxygen is determined by a difference in an amount of oxygen in the gas mixture before extraction and amount of oxygen in the gas mixture after extraction. The glass melting furnace (12) comprises burners (13), and a ceramic membrane for separating oxygen (14) from a gas mixture. Combustion energy is partially produced by oxy-combustion during heating. The flow of oxygen supplied to the burner is regulated by characteristics including temperature, pressure and flow of the gas mixture. The oxygen separation is carried out at 600-950[deg] C under a pressure of 1x 10 6>Pa. The flow of oxygen is determined by a difference in an amount of oxygen in the gas mixture before extraction and amount of oxygen in the gas mixture after extraction. The measure of amount of oxygen in the gas mixture after extraction is carried out using a probe type ceramic oxide electrode. The supply of oxygen to the burner is assisted by an additional oxygen unit with a tank. The additional supply of oxygen is carried out by direct injection in the burner so as to maintain the burner during an interruption of supply of oxygen extracted on the membrane.
